Clinical research on postoperative efficacy and related factors of early simulation hyperbaric oxygen therapy for severe craniocerebral injury

In order to discuss the clinical efficacy of simulation hyperbaric oxygen therapy(HBOT) for severe craniocerebral injury and analyze the related factors of it, 108 patients who transferred to our department during December 2010 - December 2014 for ventilator treatment after operation of severe craniocerebral injury were taken as the subjects of the study. These patients were divided into conventional treatment group and simulation hyperbaric oxygen therapy group to contrast the curative effects. At the meantime, GOS score and length of stay in intensive care unit (ICU) of two groups 6 months after treatment, as well as changes in the indexes of the HBO group during treatment were performed statistical analysis. Then factors affecting prognosis of simulation HBOT were performed regression analysis and principal component analysis. The results showed that when compared to the control group, differences in cases with four GOS score and one GOS score in the treatment group were significant (p<0.05). Jugular venous oxygen saturation (SjvO2), jugular bulb oxygen partial pressure (PjO2), arterial partial pressure of oxygen (PaO2) and arterial oxygen saturation (SaO2) of the simulation HBO group before the first time treatment on the first day and after the first time treatment on the third day were significantly increased, with statistical significance (p<0.05); serum lactic acid (Lac) and blood glucose (Glu) decreased significantly (p<0.05). Prior to and during the first treatment on the first day, jugular bulb pressure (Pj) and central venous pressure (CVP) had no significant difference (p>0.05). Regression analysis indicated that factors affecting prognosis included cerebral contusion, coronary heart disease, hydrocephalus and tracheotomy. Principal component analysis found the factors were hydrocephalus, coronary heart disease, tracheotomy, cerebral contusion, cerebral infarction and glasgow coma scale (GCS) before treatment. Therefore, stimulation HBOT can significantly improve the prognosis of patients with severe craniocerebral injury. Paying attention to risk factors in clinics and giving timely interventional treatment can reduce morbidity and mortality in patients.
